tion, illustrations and descriptions in this
manual might differ from the equipment in-
stalled in your vehicle. As such, the infor-
mation, illustrations and descriptions
contained in this manual may not be reaso-
nably relied upon in making any claims

These operating instructions form an inte-
gral part of the vehicle and should there-
fore always be kept inside the vehicle and
passed on to the new owner if the vehicle
is sold.
We extend our best wishes for many miles
of safe, pleasurable driving.

Operating safety
WarningG
Any alterations made to electronic compo-
nents and the software can cause malfunc-
tions.
The radio, amplifier, CD player*, CD chang-
er*, and telephone* are interconnected.
When one of the components is not opera-
tional or has not been removed/replaced
properly, the function of other components
may be impaired.
This condition might seriously impair the op-
erating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
WarningG
In order to avoid distraction, which could
lead to an accident, system settings should
be entered with the vehicle at a standstill.
The driver should only operate the system
when traffic conditions permit.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your car
is covering a distance of 50 feet (approxi-
mately 14 m) every second.
MCS supplies you with the information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we encour-
age the driver to stop the vehicle in a safe
place before answering or placing a call, or
consulting the MCS screen to read naviga-
tional maps, instructions, or downloaded in-
formation.
While the navigation system* provides di-
rectional assistance, the driver must remain
focused on safe driving behavior, including
attention to traffic and street signs, and
should utilize the system's audio cues while
driving.
The navigation system* does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. This al-
ways remains your personal responsibility
when you drive.DVD maps do not cover all ar-
eas nor all routes within an area.
